Russian Sea Urchin

When a female is double fisted by her partner and the fingers are then extended so as to resemble a sea urchin.

Derived from a double version of the Russian starfish

She bragged that she could totally take a Russian starfish, so I gave her a Russian Sea Urchin and she squealed.

Sea Urchin

Slang term for semen, due to the texture of the sushi form of this spiny echinoderm being very similar to that of human male ejaculate, like that feeling when rubbed in between your fingers, but in your mouth.

Also referred to as "Urchin".

"Luckily the suspect left a good sea urchin sample in the tea kettle after stealing all the footwear in the house."

"Wow, she is hurtin' for some urchin."

"Sea Urchin anyone?"

"When using a condom be sure to squeeze the reservoir tip so there is no air in it because the condom may malfunction when the sea urchin is released into it."

"I just urchinned my pants."

Sea Urchin

A form of making love under water in a replica of a giant oyster, without a breathing aparatus. Frequent breaths are needed in order to stay alive.

My lover and I were engaged in a very dangerous, but erotic, sea urchin.
